Terry Delaney has two things working against his efforts to break into the Forest Lake Little League -- a weak throwing arm and the color prejudice of team leader Tony Casterline. Everything else, however -- from the sympathies of friends, parents and coach to the breaks of the game -- goes Terry's way, insuring that benchwarmers can get mild satisfaction from being on the right side without missing a minute of the play-by-play. Fungo practice for rookie readers.
